Hi -
Just a quick note on the Vizuals.
Actionscript 3 (FlashCS3) now offers this inside
the sound class. So if you're a computer
person you could build a nice viz program
that could use either computer loaded sounds/music
or a microphone (or mic jack).
If you went this route, you could customize your viz,
or even make a different one for each song! -crazy.
I plan on building one for my own loop rig in the
future (when I can actually afford a LCD projector).
